    I'm excited to see where all of this goes. Whichever fueling method wins out, it'll likely be met by other efficiency improvements - like the autonomous car designs I've been seeing that are meant to carry only cargo rather than people. Right now the biggest energy loss comes from everyone believing they need to drive their 4,000 lb Grand Cherokee down the road to grab a loaf of bread.

    Bravo! Very well explained. You summarized my entire semester in 13 minutes!

    You compared hydrogen refueling time at a fueling station with battery charging times at home 🤥.

    You "avoid" mentioning that by making hydrogen from wind and sun we use energy that we allready ignore and loose anyway. So use as much wind and solar energy as you like to make as much hydrogen as you like... its free. We can make many hydrogen production spots arround the globe smaller or larger and that minimizes the cost of delivering the fuel.

    How much energy is getting lost on transporting the weight of the batteries in ECV which is almost 25% of the car?

    Cars in general just aren't efficient forms of transport because your moving a 2 ton hunk of metal when all you need to move is a ~150 lb human

    In Hydrogen cars the energylosses from the fuel cells are used for heating, because of that their range doesn't decrease in winter times.

    What about the energy loss in the production of electricity. Coal/solar/wind to electrical energy isn't very efficient

    I'd like to see a comparison of the cost benefits of Lithium and zinc rechargeable batteries.

    You are forgetting the cost and lifetime of batteries and fuelcells.

    What about production costs in terms of energy, money, and co2?

    You can't add percentages like that!

    Thank you very much indeed for your explanation. I just have one suggestion: to take into consideration the production costs and the life cycle of the batteries and the power and another resources, consumed in it, and the cost of further utilization of them.

    You forget the production of lithium ion batteries and the production of fuel cells

    think you forgot to add in grid to the FCV at the end, but still works out same. Great video.

    So what is the efficiency of producing petrol/gas, including oil well costs to final product?
